Abstract
The invention discloses a single-beam UV-visible spectrophotometer, which comprises a pedestal (1), a housing cover (2), and a monochromator (2) with a cover, a heat radiator (6), a lamp room assembly (5), a power transformer (10), a receiver (16) and a filter assembly (19), which are arranged on the pedestal (1). The single-beam UV-visible spectrophotometer is characterized in that the filter assembly (5) is arranged in the cover body of the monochromator (2). A filter disc of the conventional spectrophotometer arranged in a light incident position of a lamp room is moved to the cover body of the monochromator, and such arrangement can effectively prevent the disadvantages existing in conventional spectrophotometer such as contamination, deliquescence and mildew of the filter, and is more effective in processing stray light interfering the detection result, thus improving the monochromatic light detection effect.
Description
Technical field
The present invention relates to a kind of spectrophotometer, especially a kind of single beam ultraviolet-visible spectrophotometer; Belong to the optical instrument class.
Background technology
In traditional photometer design, usually filter disc is contained in the lamp house that advances optical position of lamp house, and the area of the optical filter that is adopted is also bigger.The photometer of this traditional design very easily is subjected to the pollution of environment because optical filter is directly exposed design in the lamp house of instrument, especially under the influence of the temperature environment of lamp house and humid air, is subjected to deliquescence and causes optical filter to go mouldy.Finally not only influence photometric detection effect, and will shorten the serviceable life of instrument.
Therefore, the structural defect that how existing single speed ultraviolet-visible photometer is existed carries out necessary improvement and innovation, has both made optical filter avoid the pollution and the damage of environment, also can press the serviceable life of long whole instrument simultaneously.
Summary of the invention
This single beam ultraviolet-visible spectrophotometer; Comprise base 1, outside housing cover 2 and be arranged on band cover monochromator 3, heating radiator 6, lamp room component 5, power transformer 10, receiver 16 and optical filter box 19 on the base 1, it is characterized in that: described optical filter box 19 is located in the cover body 21 of monochromator 3.
Described optical filter box 19 is made up of the five tablet filter 19-1～19-5 and the anti-dazzling screen 19-6 that are located on the filter disc dish 19-7 at least, and forms the rotatable filter assembly by the CD-ROM drive motor 19-9 that is connected with filter disc dish 19-7.
The specification of described each optical filter is 26mm * 5mm * 2.5mm.
This single beam ultraviolet-visible spectrophotometer according to above technical scheme formation; Because traditional spectrophotometer is located at the filter disc that lamp house advances on the optical position to move in the monochromator cover body, really because the improvement on this design attitude, optical filter vulnerable to pollution, deliquescence and the mouldy drawback of not only effectively having avoided traditional spectrophotometer of the same type to exist, and more effective to the processing of the veiling glare of interference detection results, play and improve the ideal role that monochromatic light detects effect.

Embodiment
This single beam ultraviolet-visible spectrophotometer as shown in the figure, it is a kind of inventive improvements to existing traditional structure list bundle ultraviolet-visible pectrophotometer.Concrete scheme is: will and be arranged on single optical filter box 19 of restrainting ultraviolet-visible pectrophotometer that the members such as band cover monochromator 2, heating radiator 6, lamp room component 5, power transformer 10, receiver 16 and optical filter box 19 on the base 1 form by base 1, outside housing cover 2 and be located in the cover body 21 of monochromator 2; And allow its camera lens face receiver 16 directions.
Described optical filter box 19 is made up of the five tablet filter 19-1～19-5 and the anti-dazzling screen 19-6 that are located on the filter disc dish 19-7 at least, and forms the rotatable filter assembly by the CD-ROM drive motor 19-9 that is connected with filter disc dish 19-7.
The specification of described each optical filter is 26mm * 5mm * 2.5mm.
